Over time organic chemists have recorded and catalogued the types and locations of IR absorptions produced by a wide variety of chemical bonds in various chemical environments. These data can be quickly referenced through tables of IR absorption ranges and compared to the spectrum under consideration.

The four-atom molecule of formaldehyde, the gas phase spectrum of which is shown below, provides an example of these terms. If a ball & stick model of formaldehyde is not displayed to the right of the spectrum, press the view ball&stick model button at the lower right.

Orekhov et al., 2001), and spectrum- and peak property-based methods (Garret et al., 1991; Johnson and Blevins, 1994; Kleywegt et al., 1990; Koradi et al., 1998), have been developed to identify peaks. ...

You then take an IR spectrum of the mull. To make a KBr ... The tiny peaks at #5 are called noise. Once you have these peak locations, you can find out what they mean by looking at a reference list of functional group locations. You will find one on page 49 of your lab manual (sixth edition) and on this web site.
